New Cast-iron or Aluminium Heads

Use ONLY standard heads or heads modified to the Negative Supercharging specs

New cast-iron or aluminium heads may be used with the Negative Supercharging Kit or Impulse Crate Engine, but the new heads should be modified to ONLY the Negative Supercharging specs. This is required to control the Negative Supercharging process and enhance the supercharging effect.

Please note that new cast-iron or aluminium heads modified to the Negative Supercharging specs produce the same increase in power as modifying used heads but add the following cost to the Negative Supercharging Kits and Impulse Crate Engines.

  • New cast-iron heads add $1,300
  • New aluminium heads add $2,300
